Harvard Citations: Cite Them Right Style Guide

Academic Integrity

2. Page number(s) for direct quotes
3. Full citation for both in-text use AND bibliography
4. Never fabricate or guess citations - flag uncertainties

Examples

@article{Hunt_2005,
  author = {Hunt, R. W. G.},
  title = {The fundamentals of color vision},
  journal = {Color Research \& Application},
  year = {2005},
  volume = {30},
  number = {3},
  pages = {171--179},

Protecting Capitalization

Use braces for proper nouns and acronyms:

title = {Understanding {COVID-19} impacts on {European} economies}

Common Errors

Wrong

• [2020] - Use round brackets: (2020)
• "quote" (Author, 2020) - Missing page: (Author, 2020, p. 45)
• Understanding Climate Change - Use sentence case: Understanding climate change
• Available at: URL - Missing access date: (Accessed: 15 March 2023)
• (Author, 2020, pp. 45) - Single page uses p.: (Author, 2020, p. 45)

Right

• Round brackets for all dates and access dates
• Page numbers for ALL direct quotes
• Sentence case for titles (capitalize only proper nouns)
• Access dates for ALL online sources
• p. for single page, pp. for page ranges
